  The decorative member 9 is configured in a rectangular (for example, rectangular) frame shape, and covers the peripheral edge 31 of the opening 29 of the ceiling 3 when viewed from the indoor side of the bathroom 1. Therefore, as shown in FIG. 2, a part of the decorative member 9 is exposed to the indoor side of the bathroom 1.

  The attached member 11 is also formed in a quadrangular (for example, rectangular) frame shape, and is fixed to the back side of the ceiling 3 by screws or the like (not shown). The air conditioner body 7 shown in FIG. 3 is fixed to the attached member 11 with screws (not shown). The decorative member 9 is locked and fixed to the attached member 11 as described later.

  A plurality of locking portions 17 are provided on the back surface side of the decorative member 9, and the decorative member 9 including the plurality of locking portions 17 is integrally formed of resin (for example, polypropylene). The locking portion 17 is provided so as to protrude upward from the back surface side of the decorative member 9.

  The decorative member 9 is provided with eight locking portions 17. Specifically, in four sides of the square frame-shaped decorative member 9, one locking portion is provided in the center of each side, and in each of the four corners of the decorative member 9, 1 A number of locking portions 17 are provided. That is, the latching | locking part 17 is provided in the center of each side part, and the both ends of the extension direction of each side part.

  The mounted member 11 has an opening 19 in which the locking portion 17 of the decorative member 9 is locked. Specifically, eight openings 19 are provided so that each locking part 17 can be locked, and each opening 19 is formed corresponding to the position of each locking part 17. ing.

  An opening 29 is provided in the ceiling 3, and the attached member 11 is fixed to the back surface side of the ceiling 3 with a screw or the like (not shown) along the peripheral edge 31 of the opening 29. Then, the decorative member 9 is locked to the attached member 11 fixed in this way through the opening 29 of the ceiling 3.

  Then, the structure of the latching | locking part 17 is demonstrated in detail. FIG. 5 is an enlarged perspective view of the locking portion 17.

  One locking portion 17 has a pair of leg portions 23 and a pair of bulging portions 21. The leg portion 23 and the bulging portion 21 are integrally formed of resin. The pair of leg portions 23 are spaced apart from each other along the outer peripheral direction of the frame-shaped decorative member 9 (the extending direction of one side portion). Similarly, the pair of bulging portions 21 are spaced apart from each other along the outer peripheral direction of the decorative member 9 (facing each other).

  The leg portion 23 extends upward from the back surface of the decorative member 9. The bulging portion 21 is provided at the tip portion on the upper side of the locking portion 17. The leg portion 23 is provided between the bulging portion 21 and the back surface of the decorative member 9, and integrally connects the bulging portion 21 and the back surface of the decorative member 9.

  The bulging part 21 bulges outward from the leg part 23. Here, outward represents the opposite side of the side where the pair of bulging portions 21 (the pair of leg portions 23) face each other. Further, the two bulging portions 21 are locked to the corresponding one opening portion 19, and the bulging portion 21 opens in a state where the locking portion 17 is locked to the opening portion 19. It is configured to bulge outward from the portion 19. In this way, the outer surfaces 212 of the bulging portions 21 that bulge outward are positioned more outward than the outer surfaces of the leg portions 23. Further, the lower surface 211 of the bulging portion 21 is configured to incline downward toward the outside.

  The leg portion 23 has a bent portion 25 at the approximate center in the height direction. In the pair of leg portions 23, the interval between the lower portions (base side) below the bent portions 25 is smaller than the interval between the upper portions above the bent portions. The upper part of the leg part 23 is bent outward from the lower part.

  A corner is formed between the lower surface of the bulging portion 21 and the outer surface of the leg portion 23.

  The leg part 23 has elasticity and functions like a leaf spring that is elastically deformed when an external force is applied to the bulging part 21.

  As shown in FIG. 5, the engaging portion 17 is provided with a connector 27 as a separation distance regulating member. The connecting tool 27 connects the pair of bulging portions 21 so that the distance between the pair of bulging portions 21 locked to the opening 19 does not change. Here, the separation distance represents a distance between arbitrary portions located at the same height on the inner surface or outer surface of the pair of bulging portions 21.

  The connector 27 is formed integrally with one of the pair of bulging portions 21. That is, the connector 27 is integrally formed of the same resin material as that of the locking portion 17. The connector 27 may be configured separately from the locking portion 17.

  In the example shown in FIG. 5, the connecting device 27 is provided integrally with the upper end portion (tip portion) of one (right side) bulging portion 21 via a thin portion, and the thin portion serves as a fulcrum (center axis). Thus, the first state in which the pair of bulging portions 21 are coupled and the second state in which the pair of bulging portions 21 are not coupled are selectably movable.

  The fitting convex part 22 is provided in the upper end part (front-end | tip part) of the bulging part 21 which is not integrally connected with the connection part 27 among a pair of bulging parts 21. As shown in FIG. On the other hand, a fitting concave portion 28 that can be fitted to the fitting convex portion 22 is provided at the distal end portion of the connecting portion 27.

  As shown in FIG. 7C, which will be described later, the connecting portion 27 is fitted into a pair of bulging portions by fitting the fitting concave portion 28 of the connecting portion 27 and the fitting convex portion 22 of the bulging portion 21 together. The first state in which 21 are connected to each other is taken.

  6 is a right side view of the locking portion 17 shown in FIG.

  In a state where the locking portion 17 is locked to the opening 19 of the attached member 11, the lower surface 211 of the bulging portion 21 abuts on the upper surface of the periphery of the opening 19 in the attached member 11. The broken line shown in FIG. 6 represents the position of the upper surface of the attached member 11.

  In FIG. 6, the right side of the locking portion 17 is the inner side of the frame-shaped attached member 11 and the frame-shaped decorative member 9, and the left side is the outer side of the attached member 11 and the decorative member 9. When the bulging portion 21 is viewed from the outer surface side, the lower surface 211 of the bulging portion 21 is inclined with respect to the upper surface (broken line) of the attached member 11, and the inner surface of the lower surface 211 of the bulging portion 21 is inward. The side portion 211b is positioned below the outer side portion 211a. The inclination angle of the lower surface 211 of the bulging portion 21 with respect to the upper surface of the mounted member 11 is, for example, 1 ° or less. If the inclination of the lower surface 211 is formed by a draft that always occurs when the decorative member 9 is integrally molded by injection molding, it is not necessary to perform post-processing to provide an inclination after molding, so that the manufacturing cost is reduced. Can be suppressed. In addition, when the inclination is formed on the lower surface 211 by such a method, it is preferable that the inclination angle of the lower surface 211 is set to 0.5 ° or more in consideration of ease of extraction when the molded product is extracted from the mold.

  Next, a method for locking the locking portion 17 to the opening 19 will be described.

  FIGS. 7A to 7C are schematic views for explaining a method of locking the locking portion 17 of the decorative member 9 to the opening 19 of the attached member 11. FIG. 7A shows a state before the bulging portion 21 is inserted into the opening 19. FIG. 7B shows a state after the bulging portion 21 is inserted into the opening 19. FIG. 7C shows a state in which the two bulging portions 21 locked to the opening 19 are connected by the connecting tool 27.

  As shown in FIG. 7A, the two bulging portions 21 are in a second state where they are not connected by the connecting tool 27 before the locking portion 17 is inserted into the opening 19.

  Subsequently, the locking portion 17 is inserted into the opening 19 so that the two bulging portions 21 enter the opening 19. At this time, as shown by the broken line in FIG. 7B, the outer surfaces 212 of the two bulging portions 21 abut against the peripheral edge 20 of the opening 19 and the distance between the two bulging portions 21 decreases as the insertion is performed. As a result, the two bulging portions 21 are inserted into the opening 19. In addition, the change of the separation distance of the two bulging parts 21 arises when the bending degree of the bending part 25 becomes small (bending becomes loose) by elastic deformation.

  As shown by the solid line in FIG. 7B, after the two bulging portions 21 enter the opening portion 19, the bent portion 25 that has been elastically deformed is restored to the original bending degree, and the two bulging portions are restored. When the lower surface 211 of the portion 21 rides on the upper surface of the attached member 11, the lower surface 211 of the bulging portion 21 is hooked on the peripheral edge 20 of the opening 19, and the locking portion 17 is locked to the opening 19. .

  And as shown in FIG.7 (c), the coupling tool 27 is rotated and the fitting recessed part 28 of the coupling tool 27 and the fitting convex part 22 provided in the upper end of the bulging part 21 are fitted, By bringing the two bulging portions 21 into a connected state (first state), the locking operation of the locking portion 17 to the opening 19 is completed.

  FIGS. 8A to 8C are schematic views for explaining a method of attaching the decorative member 9 to the attached member 11. FIG. 8A shows a state before the locking portions 17 are inserted into the openings 19, and FIG. 8B shows a state after all the locking portions 17 are inserted into the corresponding openings 19. FIG. 8C shows a state after the two bulging portions 21 in the respective locking portions 17 are connected by the connecting device 27.

  In the order shown in FIG. 8, all the locking portions 17 are locked to the corresponding opening portions 19, so that the decorative member 9 is attached to the attached member 11 fixed to the peripheral edge portion 31 of the opening 29 by a screw or the like in advance. Can be locked and fixed.

  The work for fixing the attached member 11 to the ceiling 3 and the work shown in FIGS. 7A to 7C and FIGS. 8A to 8C are performed before the ceiling 3 is assembled to the upper part of the bathroom 1. Is called. Therefore, the operation of inserting the bulging portion 21 into the opening 19 and the connecting operation of the two bulging portions 21 by the connecting tool 27 can be performed by the operator.

  FIG. 9 is an enlarged view of a portion B surrounded by a broken line in FIG. FIG. 10 is a side sectional view of the locking portion 17 of FIG. 8C viewed from the right side in a state where the air conditioner 5 is attached to the ceiling 3. As shown in FIGS. 9 and 10, the outer end of the flange portion 12, which is the peripheral portion of the frame-shaped decorative member 9, is pressed against the surface of the ceiling 3 at the peripheral edge of the ceiling opening 29. The lower surface of the flange portion 12 functions as a decorative surface that hides the edge of the ceiling opening 29.

  One locking portion 17 is provided on the inner side of the flange portion 12 of the decorative member 9 and at a position near the flange portion 12 (in the vicinity of the flange portion 12), as shown in FIG. As described above, the outer end of the lower surface 211 of the bulging portion 21 is pressed against the upper surface of the attached member 11.

  Therefore, the ceiling 3 and the attached member 11 are sandwiched between the flange portion 12 of the decorative member 9 and the lower surface 211 of the bulging portion 21. The restoring force due to the elastic deformation of the flange portion 12 gives a force for sandwiching the ceiling 3 and the attached member 11 between the bulging portion 21 and the flange portion 12.

  In this embodiment, the ceiling 3 and the mounted member 11 are sandwiched between the bulging portion 21 whose lower surface 211 is inclined outward and the flange portion of the decorative member 9 as described above. Even if the air conditioner body 7 vibrates due to rotation, driving of a motor that rotates a fan, or the like, rattling of the flange portion 12 of the decorative member 9 can be suppressed and generation of noise can be suppressed.

  In the present embodiment, since the bent portion 25 is formed between the bulging portion 21 and the back surface of the decorative member 9 in the locking portion 17, the bending portion 25 is bent when the bulging portion 21 is inserted into the opening portion 19. The leg portion 23 can be deformed around the portion 25. Therefore, the deformation can be caused not at the base of the leg portion 23 but at a position closer to the bulging portion 21 in the leg portion 23. Thereby, when inserting the bulging part 21 of the latching | locking part 17 in the opening part 19, as shown with the broken line of FIG.7 (b), it temporarily raises the lower surface of the bulging part 21 outward. It becomes easy to make it incline. Therefore, when inserting the bulging part 21 into the opening part 19, it becomes possible to lock the latching | locking part 17 to the opening part 19 with a smaller insertion amount, and can improve latching workability | operativity.

  Further, in the present embodiment, in a state where the plurality of bulging portions 21 are locked to the opening 19, the plurality of bulging portions 21 are separated from each other so that the distance between the plurality of bulging portions 21 is not reduced. A connector 27 is provided to maintain the distance above a predetermined distance. With such a simple configuration, in a state where the plurality of bulging portions 21 are locked to the opening 19, the plurality of bulging portions 21 locked to the opening 19 are displaced inward. Therefore, the decorative member can be prevented from falling. Further, the shortest distance L in the vertical direction between the lower end of the bulging portion 21 and the flange portion 12 covering the peripheral edge portion 31 of the ceiling opening 29 in the decorative member 9 is aged due to deformation of the locking portion 17 or the like. The backlash of the decorative member 9 in the vertical direction can be suppressed over a long period of time without becoming large.

  In this embodiment, the connecting tool 27 is formed integrally with one of the two bulging parts 21, and the connecting tool 27 connects the two bulging parts 21. The first state to be rotated and the second state in which the two bulging portions 21 are not connected to each other are selectably rotated. Therefore, when the two bulging portions 21 are connected, there is no fear that the connecting tool 27 may drop or the connecting tool 27 may be lost, so that workability when attaching the decorative member 9 to the attached member 11 is improved. be able to. Further, when the plurality of bulging portions 21 are inserted into the opening portion 19, the insertion is facilitated by setting the second state, and even when the connecting tool 27 is formed integrally with the bulging portion 21, The workability at the time of engaging the decorative member 9 does not deteriorate.

  In this embodiment, as shown in FIG. 10, the inner portion 211 b of the decorative member 9 on the lower surface 211 of the bulging portion 21 is positioned below the outer portion 211 a of the decorative member 9. ing. More specifically, the lower surface 211 of the bulging portion 21 is configured to be inclined downward from the outer side to the inner side of the decorative member 9 in a direction orthogonal to the outer peripheral direction of the decorative member 9. Accordingly, the inner portion 211b has a higher pressing force on the upper surface of the attached member 11 than the outer portion 211a. The outer portion 211a floats from the upper surface of the attached member 11, or is in contact with a weaker force than the inner portion 211b.

  Next, a second embodiment of the air conditioner 5 according to the present invention will be described. In 2nd Embodiment, since only the latching | locking part 17 and the connection tool 27 of 1st Embodiment differ, since other structures are the same as 1st Embodiment, description is abbreviate | omitted.

  FIG. 11 is an enlarged perspective view of the locking portion 33 of the second embodiment and the fitting 41 fitted in the locking portion 33.

  The locking portion 33 is formed of a resin and has a cylindrical cylindrical leg portion 35 that is discharged upward from the back surface of the decorative member 9 and a plurality of bulging portions 37 provided at the tip of the cylindrical leg portion 35. ing. The plurality of bulging portions 37 are formed integrally with the cylindrical leg portion 35 and are provided at predetermined intervals in the circumferential direction.

  On the other hand, the fitting tool 41 is formed of resin, and is configured by integrally providing a cross-shaped cross portion 45 on a donut-shaped base portion 43.

  FIG. 12 is a perspective view of a state in which the fitting tool 41 is fitted in the locking portion 33. As shown in FIG. 12, in a state where the fitting tool 41 is fitted in the locking portion 33, the cross portion 45 of the fitting tool 41 enters the gap 39 between the plurality of bulging portions 37 of the locking portion 33. It becomes a state. Since the width of each of the two linear members 47 constituting the cross portion 45 is configured to be substantially the same as the width of the gap 39 between the plurality of bulging portions 37, the locking portion In the state in which the fitting tool 41 is fitted in 33, the plurality of bulging portions 37 are regulated so that their separation distance is not reduced even when an external force is applied. That is, it is regulated so that the separation distance is not less than a predetermined distance.

  Therefore, as in the first embodiment, the engaging portion 33 is inserted into, for example, a circular opening provided in the attached member 11, and the engaging portion 33 is engaged with the opening. By fitting 41 into the engaging portion 33, the decorative member 9 can be prevented from dropping from the attached member 11.
